Summary: Process hangs while running file system stress test on
XFS
Kernel Version: 2.6.11-rc3-mm1
Status: NEW
Severity: normal
Owner: xfs-masters at oss.sgi.com
Submitter: sharyathi at in.ibm.com
CC: sglass at us.ibm.com
Distribution: SLES 9
Hardware Environment: x235, 2 way, memory 1.5 GB
Software Environment: 2.6.11-rc3-mm1
Problem Description: We started stress tests on mounted XFS file system, after
5-6 hours we noticed rm command getting hung and we are not able to delete all
the files from the XFS file system and the file system couldn't be unmounted.
The test process can be killed but even after that the rm command called by the
test process still remained.
The stack trace of the rm process is as follows:

Steps to reproduce:
mount a xfs file system
and run File System Stress test on the File System.
after running it for 5-6 hours we found out we were not able to unmount the file
system.
Note: We encountered this problem after following these steps, not sure if the
deffect can be reproduced.
